passed, the override function becomes invalid. When the muting lamp diagnosis function is invalid, the muting

3-9 Functions Using Handy Controller (SFB-HC) (Optional)

This device enables to set each function using the handy controller (SFB-HC) (optional). The
settable functions and the factory setting of each function are as follows.
For details, refer to the instruction manual enclosed with the handy controller.
● Fixed blanking function
This function enables to protect the control output (OSSD 1 / 2) from turning into OFF even
though the specific beam channel is blocked.
The factory setting is set to be invalid for the fixed blanking function.
● Floating blanking function
This function enables to protect the control output (OSSD 1 / 2) from turning into OFF even
though the number of the blocked beam channels are lower than that of the setting beam
channels. 1, 2 or 3 beam channels are settable as the blocking beam channels.
The factory setting is set to be invalid for the floating blanking function.
Both fixed blanking function and floating blanking function are settable simultaneously.
● Emission amount control function
The two modes, normal mode and short mode, can be set / changed by controlling the emis-
sion amount. The factory setting is set to the normal mode for the emission amount control
function.

3 to 4 sec. (Note)
Among the functions, the contents related to the safety distance such as the size of
the minimum sensing object are varied depending on the setting condition. When
setting each function, re-calculate the safety distance, and make enough space larg-
er than the calculated safety distance. Failure to do so might cause the accident that
the device cannot stop quickly before reaching the dangerous area of the device,
resulting in the death or serious injury.
